A model calibration on the basis of the data from both stressed and irrigated durum wheat was carried out using a proposed model that utilizes the response of stomatal conductance (Ks) to net radiation (Rn), vapour pressure deficit of the atmosphere (VPD), and leaf water potential. The calculated parameter values appeared to be higher in well-watered plants for (1) the maximum of Ks under non-limiting light conditions and the rate of reaching this maximum and (2) the minimum threshold of leaf water potential for the beginning of stomatal opening. Lower values in stressed plants for these parameters: (1) rate of stomata closing at the increasing VPD and (2) rate of stomatal response to increasing leaf water potential were observed. Some speculations on the possibility of utilizing the values of the considered physiological traits in breeding for drought resistance are discussed
